METHOD F APPLYING i MATERIAL Application led August 11, 1931. Serial No. 556,462.

This-'invention relates to the method ofv treatingjoints in a structure and in particular to the method of filling the joints or cracks in a building 'structure with a material of a preservative nature in order to prevent deterioration inside the structure wall and to prevent thepassage of moisture through the cracks in the wal1,'and will prevent waste of material of application and will be effective in sealing said joints, cracks or `deep pores.

In building structures already erected that are not weatherproof and consequently adm it moisture, the joints in' the brick work or 1n the structural work, or in the structuralelement, must be filled from the exterior of the building. There are a great many dierent kinds of material that can be applied to form a chemical precipitate or provide a waterproofing or a preserative or the material used 23 may be a combination of chemicals to forma chemical precipitate in one instance and 1n another instance, the chemical would congeal around the precipitate and create a packing of waterproofing. Material may also be pro- 23 vided acting as a combination of preservative, precipitate and waterproofing.

There are a great many different kinds of vmaterial that can be applied such as heated Wax, fluosilicates, stearates mixed with naph- 33. tha, benzine substitutes, and so on, and being nearl all in liquid form carrying a waterproo ng in suspension, have heretofore'been applied by a brush or spray. In the case of the brush, the amount of material that gets into the joint is ineective and in the case of a spray, there is a great waste of material and not much force. In the use of the brush, also, there is considerable waste 1of material and the cracks or joints are filled for a veryshort [-0 distance from'the surfaceand do not provide the necessary packingin the joint that is necessary to render the building moistureproof and prevent the structural elements being properly preserved.

`The important feature of my invention is that it is distinctive from VSpraying a wall as the spray air pressure could not be strong enough to blow a liquid through a crack and at the same time be practical for spraying.

My improved process consists of applying a liquid to a wall in any manner permitting the liquid to run down the wall until it reaches a crack or oint at which point a separate air stream is applied from the exterior in such a way as to force the liquid into the crack or joint and in this way, liquid throughout the entire distance of the crack may be blown into the crack so that the crack is filled completely through the wall of the structure. The liquid is guided to the crack by the air stream and held at the crack until the liquid Hows into and completely fills the crack to refusal.

With these and other objects in view, the invention comprises certain methods hereinafter described and then particularly pointed out in the claims;

' Figure 1 is a view in side elevation of a structure treated in accordance with my improved process, and

Figure 2 is a view in front elevation of the structure illustrated in Figure 1 showing the application of the fluid through the medium of a nozzle or spray of liquid to the wall and forcing of the liquid into the joints in the structure.

My improved process or method therefore,

consists in first brushing the material on the exterior surface of the structure to bev treated so that the material will run down the surface in little streams. The next step is the use of a separate air stream blowing against thel surface with a pressure ranging approximately between three to fifty pounds pressure. The air pressure at the point of contact with the wall is reduced in operation by holding the air nozzle further from the wall and is increased conversely by bringing the air nozzle nearer to the wall-the lower pressures are used to guide. the material across the face of the wall and to the crack or section to be treated and lthehigher pressure is used to force the material into the crack-the application and operation being a continuous movement of the air nozzle to the surface of the wall as the liquid is :guided to and forced into the crack. The air blast is strong enough to keep the stream fromrunning down the face of the building so that when the stream reaches the air blast,

or is guided by the air blast, every bit of material willv be blown into cracks or joints of the structure and the pressure employed will be such that the material will be forced all the way through the cracks to refusal thus eliminating the waste due to spraying and applyin alone with a brush and permitting the luse o a high air pressure that would not be possible with a spray to force the material into the joints or cracks.

By painting or spraying the surface only, the ordinary capillary action must be depended upon to reach inside the crack. In the case where the wall is damp or is wet from a previous coat of material, or in the case where the crack is of such nature that the capillary attraction is not effectively drawing moisture into the wall, the paint or spray coat merely remains on the surface. With my process,l the liquid enters into the crack by virtue of the force of the air blast and the natural capillarity of the wall is not depended upon to any extent, and by this process we receive a more uniform application for this reason.

It is evident that this process is distinctive from the spraying of a wall as the spray air ressure cannot be made strong enough to Elow a liquid through a crack and at the same time be practical for spraying without considerable waste. Also painting the sur.

face with a brush or other implement only lls the crack or joint for a very short distance from the surface and is not effective in carrying out the treatment proposed by the use of the material employed.

My process consists in allowing a liquid to run down to the crack and then blowing.' it into the wall as a liquid with an air stream, or guiding the liquid to the crack with the air stream and then blowing it into the crack with the same or another air stream.

My invention is applicable for the treatment of any type of wall whether concrete, brick, ceramics or clay products, stone, mortar, manufactured combination blocks or combinations of masonr or metal and is highly effective in applying material for various purposes to the joints on the exterior wall of a structure. It might be mentioned that the invention is also applicable to interior walls but the waterproofing and treatment of structure walls is usually made on the exterior surface, as the inner wall of older buildings usually is covered with other parts of the building structure.

The material to be forced into the joints or crevices may be separate and distinct liquids to form a chemical precipitate in the crack or three separate liquids may be applied, two of which would form the chemical precipitate and the other would congeal around the precipitate and create a packing of waterproong in the crack. It is also possible to vthe wall of a fillin on with a use a combination of preservative, precipitate and waterproofin materials.

It is evident, there ore, that I have provided a method of treating walls of a structure which consists in applying to the eXterior surface of the wall, a material that will trickle down the surface of the wall to the point where an air blast is ap lied to drive the liquid or material into crac s, crevices or joints in the structural element, the air ressure being effective to completely fill the joint with the material throu h the thickness of the wall and a mdtho which eliminates waste, is more quickly and effectively applied and lends itself to the continuous working on a wall of several different materials to carry out thek diierent treatments of a structure.

It is evident also that while the liquid is running down the face of the wall, an air stream may be used to guide this liquid to the portion of the wall that requires treatment or to a `crack, and the same or a separate air stream can be used to drive it into this crack and concentrate at this point of weakness in lthis wall the greatest quantity of material in a logical manner.

It is evident also that my method anticipates the application to the cracks or joints of material of a plastic, semi-plastic or flui nature and thereafter applyin the air blast to the cracks or joints to comp etely fill the same with the material by forcmg the same as far as posslble into the cracks or joints.

Ordinarxplastic compounds nominally put ife, calking instrument or calking gun, can with this process be thinned with a thinner such as benzine, linseed oil, fish oil, China-wood oil,or other thinners used for thlnnin calking compounds, and then blown into t e crack with the -air stream.

'My invention is not to be restricted to the preclse details of the Amethod employed since various modifications may be made therein without departing from the scope of the in'- vention or sacrificing the advantages derived from its use.

What I claim is 1. The herein described method of treating the wall of a structure consisting in applying Huid material to the wall and thereafter applying an air blast to the fluid to force it into the wall crevices.

2. The herein described method of treating the wall of a structure consisting in applying a fluid material to the wall so that the fluid streams down the wall, and applying an air blast at the lower edge of the stream to arrest the flow thereof and force the same into a ]o1nt.

In testimony whereof I ax my signature.
